Tuberías con costura o sin costuras ¿cuáles utilizar?
En el mundo industrial las tuberías son necesarias y altamente utilizadas para el transporte de fluidos, muchos han sido los estudios realizados para mejorar sus aplicaciones hasta el día de hoy. Si, te encuentras frente a un diseño de una tubería de 4” para un fluido altamente corrosivo, pero a baja presión, ¿sugerirías tubería con…
Read MoreQ&A – CAD Layers and Productivity
CAD Layers Is there some type of standard CAD layering for process piping. I can find standards for electrical and architectural but nothing for piping. Do you know where I can find them if they exist? This question has come up many, many times over the years. In the 70’s, 80’s and 90’s when the available…
Read MoreHow can one know whether stub-in/stub-out or fitting connection is required or not for branch connection & in fitting type whether one should go with Tee or o’let?
Stub-out is not a correct term, this should be stub-on. Functionally if you are the piping layout designer doing piping layout then you use the information supplied on the “Branch Selection Tables” provided by the Piping Material Engineer (PME) in the Line Class specs. Functionally if you are the PME developing the “Branch Selection Table”…
Read MoreIs an eccentric reducer normally only used at pump suction? It is ever used for any other cases? If so, give the details.
No, eccentric reducers are also used for line size reductions in pipeways in order to keep the bottom of pipe (BOP) the same and in proper contact with the pipe supports. It is also used in other cases. Eccentric reducers are used on both the inlet and outlet piping to some other equipment. The equipment…
Read MoreQ&A – What is a bridle?
A Bridle is a special piping arrangement done by the piping designer to hold the Level Instruments for a Vessel or Tank. Level instruments such as: Level Glass (or Gage), Level Transmitter, Level Controller and Level Alarm. See example of an Instrument Bridle below.
Read MoreQ&A – What is the application of a control valve? And what are the main types and parts?
The purpose of a “Control” valve is to control. It might control flow, level, pressure or temperature depending on the purpose of loop it is installed in. The valve itself is normally a “globe” type valve body but with an air or electro-pneumatic operator. This operator is controlled through a loop that includes a primary…
Read MoreQ&A – For column overhead line, why is the first support always a Rest support?
The simple answer is “That’s all that is needed”. You have to understand the full picture of the top of the vessel along with the configuration of the “Overhead Line”. a) If the “Overhead Line” exits the vessel from a side nozzle and turns down with an elbow then you want a solid (Rest) support…
Read MoreQ&A – What is a Back Pressure Turbine and what is a Condensing Turbine?
Back Pressure Turbines: a type of steam turbine that is used in connection with industrial processes where there is a need for low or medium pressure steam. The high pressure steam enters the back pressure steam turbine and while the steam expands – part of its thermal energy is converted into mechanical energy. The mechanical…
